Supported Absorption of CO2 by Tetrabutylphosphonium Amino Acid Ionic Liquids
Open accessAbstract
A new type of “task specific ionic liquid”, tetrabutylphosphonium amino acid [P(C 4)4][AA], was synthesized by the reaction of tetrabutylphosphonium hydroxide [P(C 4)4][OH] with amino acids, including glycine, L‐alanine, L‐β‐alanine, L‐serine, and L‐lysine. The liquids produced were characterized by NMR, IR spectroscopies, and elemental analysis, and their thermal decomposition temperature, glass transition temperature, electrical conductivity, density, and viscosity were recorded in detail. The [P(C 4)4][AA] supported on porous silica gel effected fast and reversible CO 2 absorption when compared with bubbling CO 2 into the bulk of the ionic liquid. No changes in absorption capacity and kinetics were found after four cycles of absorption/desorption. The CO 2 absorption capacity at equilibrium was 50 mol % of the ionic liquids. In the presence of water (1 wt %), the ionic liquids could absorb equimolar amounts of CO 2. The CO 2 absorption mechanisms of the ionic liquids with and without water were different.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
